2020-12-08substitute: Cache and reuse connections while substituting....That way, when fetching a series of substitutes from the same server(s), the connection is reused instead of being closed/opened for each substitutes, which saves on network round trips and TLS handshakes. * guix/http-client.scm (http-fetch): Add #:keep-alive? and honor it. * guix/progress.scm (progress-report-port): Add #:close? parameter and honor it. * guix/scripts/substitute.scm (at-most): Return the tail as a second value. (fetch): Add #:port and #:keep-alive? and honor them. (%max-cached-connections): New variable. (open-connection-for-uri/cached, call-with-cached-connection): New procedures. (with-cached-connection): New macro. (process-substitution): Wrap 'fetch' call in 'with-cached-connection'. Pass #:close? to 'progress-report-port'. Ludovic Courtès
2020-03-22Remove workaround for 'time-monotonic' in Guile 2.2.2....This is a followup to e688c2df3924423b67892cc9939ca099c729d1cb. * build-aux/hydra/evaluate.scm <top level>: Remove 'time-monotonic' definition. * guix/cache.scm: Likewise. * guix/progress.scm: Likewise. * guix/scripts/substitute.scm: Likewise. * guix/scripts/weather.scm: Likewise. * tests/cache.scm: Likewise. Ludovic Courtès
2019-12-12progress: Add 'progress-report-port'....* guix/scripts/substitute.scm (progress-report-port): Move to... * guix/progress.scm (progress-report-port): ... here. New procedure. Ludovic Courtès
2019-06-24progress: Call 'time-difference' on times of the same type....Guile 2.2.5 and 2.9.2 would catch the issue. This is a followup to 88bc3c89bf5145d24c2270d2192b7be547e0024f. * guix/progress.scm (display-download-progress)[elapsed]: Pass 'current-time' the same type as START-TIME. Ludovic Courtès
2019-06-02progress: Provide the proper type for %PROGRESS-INTERVAL....The (srfi srfi-19) module of Guile 2.9.2 catches the wrong type. * guix/progress.scm (%progress-interval): Change type to TIME-DURATION. Ludovic Courtès
2018-11-16progress: Do not display the last 0B transfer when size is unknown....* guix/progress.scm (display-download-progress): Don't display anything when both SIZE and TRANSFERRED are null. Clément Lassieur
2018-11-16progress: Fix crash because of division by zero....* guix/progress.scm (display-download-progress): Handle the case where SIZE is null. Clément Lassieur
2018-10-05progress: Fix total size in "@ download-succeeded" traces....Fixes a regression introduced in 1d0be47ab680db938ac8da1ee65e1de91e198f67 whereby the total size for directories (coming from substitutes) would be 4KiB. This led the progress bar to go back to the start, typically. * guix/progress.scm (progress-reporter/trace): Add 'total'. In 'start', initialize it. Adjust 'report' to update it. Adjust 'stop' to prefer SIZE as the actual size and then TOTAL. Do not use the size of FILE as the total since that could be 4KiB when FILE is a directory. Ludovic Courtès
2018-10-04progress: Generate valid 'download-progress' traces when the size is unknown....Fixes <https://bugs.gnu.org/32895>. Reported by Ricardo Wurmus <ricardo.wurmus@mdc-berlin.de>. * guix/progress.scm (progress-reporter/trace): In 'stop', make sure SIZE is an integer. Previously we'd generate a "@ download-progress" trace with #f for the 'transferred' number when downloading files whose size is not known in advance. Ludovic Courtès
2018-09-27Add (guix status) and use it for pretty colored output....* guix/progress.scm (progress-reporter/trace): New procedure. (%progress-interval): New variable. (progress-reporter/file): Use it. * guix/scripts/build.scm (set-build-options-from-command-line): Pass #:print-extended-build-trace?. (%default-options): Add 'print-extended-build-trace?'. (guix-build): Parameterize CURRENT-TERMINAL-COLUMNS. Use 'build-status-updater'. * guix/scripts/environment.scm (%default-options): Add 'print-extended-build-trace?'. (guix-environment): Wrap body in 'with-status-report'. * guix/scripts/pack.scm (%default-options): Add 'print-build-trace?' and 'print-extended-build-trace?'. (guix-pack): Wrap body in 'with-status-report'. * guix/scripts/package.scm (%default-options, guix-package): Likewise. * guix/scripts/system.scm (%default-options, guix-system): Likewise. * guix/scripts/pull.scm (%default-options, guix-pull): Likewise. * guix/scripts/substitute.scm (progress-report-port): Don't call STOP when TOTAL is zero. (process-substitution): Add #:print-build-trace? and honor it. (guix-substitute)[print-build-trace?]: New variable. Pass #:print-build-trace? to 'process-substitution'. * guix/status.scm: New file. * guix/store.scm (set-build-options): Add #:print-extended-build-trace?; pass it into PAIRS. (%protocol-version): Bump. (protocol-version, nix-server-version): New procedures. (current-store-protocol-version): New variable. (with-store, build-things): Parameterize it. * guix/ui.scm (build-output-port): Remove.

2017-12-15progress: Rename 'erase-in-line' to 'erase-current-line'....Suggested by Danny Milosavljevic <dannym@scratchpost.org>. * guix/progress.scm (erase-in-line): Rename to... (erase-current-line): ... this. Adjust callers. Ludovic Courtès
2017-12-01weather: Use (guix progress) for progress report....* guix/progress.scm (start-progress-reporter!, stop-progress-reporter!) (progress-reporter-report!): New procedures. * guix/scripts/weather.scm (call-with-progress-reporter): New procedure. (package-outputs)[update-progress!]: Remove. Use 'call-with-progress-reporter' instead. (guix-weather): Parameterize 'current-terminal-columns'. Ludovic Courtès
2017-12-01progress: Add 'progress-reporter/bar'....* guix/progress.scm (progress-reporter/bar): New procedure. Ludovic Courtès
2017-12-01progress: 'progress-bar' accounts for brackets....* guix/progress.scm (progress-bar): Subtract 2 to BAR-WIDTH to account for brackets. Ludovic Courtès

2017-10-19Add (guix progress)....Among other things, this removes (guix utils), (guix ui), (guix config), etc. from the closure of (guix build download), as was the case since 798648515b77507c242752457b4dc17c155bad6e. * guix/utils.scm (<progress-reporter>, call-with-progress-reporter): Move to... * guix/progress.scm: ... here. New file. * Makefile.am (MODULES): Add it. * guix/build/download.scm (current-terminal-columns) (nearest-exact-integer, duration->seconds, seconds->string) (byte-count->string, progress-bar, string-pad-middle) (rate-limited, progress-reporter/file, dump-port*) (time-monotonic): Move to progress.scm. * guix/scripts/download.scm: Adjust accordingly. * guix/scripts/substitute.scm: Likewise.
